MULTIPLE-UNIT DEFLECTI NG BAR STAND FOR SWITCH AND SIGNAL OPERATING ucas.

Be it known that I, WALTER E. FOSTER, of Edgewood Park, Allegheny county, Pennsylvania, have invented a new and useful Multile-Unit Deflecting-B ar'Stand for Switch and bignai Operating Lines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part ofthis specification, in which i Figures 1, 2 and 4 are plan views showing different relative positions of the stands;

f Fig. 3 is a section on the line III-III of g- 2; Fig. 5 is a plan view'of one of the base members; Fig. 6 is a detail viewshowing a modification; Fig. 7 is a cross-section of Fig. 6; and Fig. 8 is a detail view of a further modification.

My invention has relation to multiple unit deflecting bar stands for switch and signal operating pipe lines or rods, and is designed to provide a stand of this character'which can be used for making angular bends or turns in the pipes or rods, both where the'centers of the pipes are the same before and afterturning, and also where the centerschange.

A further object of the inventionis to pro-' vide a simple stand of this character having roller bearings for the deflector bars, and which can be used reversibly or interchangeably for both right and left-hand bends.

An important featureof my invention consists in the provision of stands ofthis character having each a plurality of bearing points adapted to contact with bearing points of an adjacent similar stand in different relative positions of the two stands, thereby spacing and setting the stands in their proper position.

The precise nature of my invention will be best understood by referenceto the accompanying drawings, in which I have shown one embodimentthereof, it being premised, however, that the invention is susceptible of various other embodiments and that its design may be widely departed from in form without departing from the spirit and scope of my invention as defined in the appended claims.

In these drawings, the numeral 2 designates a number of adjacent stands embodying my invention, and consisting each of a curved formed as an integral casing, and which is Patented Jan. 26, 1909.

' provided at different points in its length with bolt holes 3, in which are placed. vertical bolts 4, upon which are mounted the bearing rollers 5 for the deflector bars 6. In- I stead, however, of employing separate bolts seated in the base in the manner described, it is obvious that studs projecting upwardly from the base may be employed, as shown in Fig. 8. These bolts are arranged in pairs, and are connected at their upper ends by the caps or housings 7 secured by nuts 8 on the bolts. The base is also provided with suitable means such as bolt holes 9, by which it may be secured to its seat on a suitable foundation. In the particular design shown in the drawing, I have shown each of the stands as having two pairs of bearing rollers 5 located on opposite sides of the center of the base. vex edge with a plurality of bearing surfaces 10 and 11, the bearing surfaces 10 being on the projections 12 and the bearing surfaces At its opposite edge the base is provided with the convex bearing surfaces 13 adapted to engage the bearing surfaces 10 and 11 of an adjacent stand.

In use, a plurality of these stands, one for each operating pipe or rod, are placed side by side, as shown in Figs. 1 and 2 with the defiector bars connecting the ends of the pipes or rods extending between the bars or bearing rollers. Where the distance between the centers of the pipes or rods is the same at both sides of the turn or bend, the stands are arranged as shown in Fig. 1, the convex hearing surfaces 13 of one base engaging the concave bearing surfaces 11 of the adjacent stand, thus forming and acting as spacers to hold the stands in parallel position. Where the distance between the centers of the pipes or rods is different at one side of the bend or turn than at the other, as shown in Fig. 2, the stands are placed as also shown in that figure, so that the convex bearing surfaces 13 of one bar rest in the concave bearing surfaces 10 of the adjacent bar.

Fig. 2 shows the relative positions of the stands where the distance between the centers is less at one side of the turn or bend than at the other, While Fig. 4 shows their arrangement when the distance between centers decreases at the opposite side of the Each base 2 is formed on its con- 11 being intermediate of said projections.

turn or bend. From these two figures, compared with Fig. 1 it will be seen that Whereas in the parallel relation of the stands as shown in the last named figure, the convex bearing surfaces 13 of one stand engage with the concave bearing surfaces 11 of the other stand intermediate its projections 12, when the stands are used With a change in centers, the bearing surfaces 13 will engage the bearing surfaces 10 at one side or the other of the bearing surfaces 11, depending upon which side of the stand the decrease in centers occurs. It Will be seen that in this manner the stands are adapted for universal use, since the distance between centers of the pipes or rods is, in practice, made according to fixed standards, only two different spacings being used. The cooperating bearing surfaces of the stands act in all the difierent positions thereof to properly space and set the stands in their correct positions, so that after the first stand has been set the others can be readily and quickly set from it.

If desired, the caps or housings 7 for the bearing rollers of each stand may be connected by a flanged housing 14. It will also be noted that the stands may be used in either right or left position.

It will be understood that the particular form or design of stand which I have herein shown and described, is illustrative only, it being obvious that various forms or designs may be made Which will operate in the manner described. I do not, therefore, desire to limit myself to this particular form or design, since I believe that I am the first to provide a stand which is capable of universal use in the manner described.

I claim 1. A deflecting bar stand having bearings for a deflector bar, and provided with a plurality of bearing portions or surfaces adapted to contact with bearing portions or surfaces of an adjacent similar stand in different relative positions of the two stands; substanlateral bearing portions or surfaces adapted r to engage the corresponding bearing portions or surfaces of an adjacent stand in different relative positions of the two stands; substantially as described.

3. A deflecting bar stand having a plurality of bearing rollers mounted thereon for the deflecting bar, said stand having its base portion provided at one side with a plurality of bearing projections, and its other side with a plurality of bearing projections and intermediate depressions also forming hearing surraces; substantially as described.

4. A deflecting bar stand comprising a curved base, a plurality of bearing rollers mounted thereon, and caps or housings for said rollers, said base having a plurality of bearing surfaces adapted to cooperate with the bearing surfaces of adjacent similar stands to space said stands in different relative positions; substantially as described.

5. A deflecting bar stand having spacing projections adapted to engage corresponding portions of adjacent stands to thereby space such stands either in a position of parallelism, or at an angle to each other; substantially as described.

6. A multiple unit deflecting bar stand, comprising a plurality of separate stands each of which is provided with bearing rollers, and which is adapted to have bearing contact with adjacent stands in three different positions thereof; substantially as described.

In testimony whereof, I have hereunto set my hand.
